10-kilovolt motor insulation system and interturn insulation structure thereof

The utility model relates to a 10-kilovolt motor insulation system and an interturn insulation structure thereof. The interturn insulation structure comprises a wire insulation layer. The wire insulation layer comprises three layers of polyester-film dry mica tapes which are wound around a copper strap wire conductor at intervals. The gaps of the first layer, the second layer and the third layer are respectively set to X1, X2 and X3, with X1 being greater than zero but not greater than 0.1mm, X2 being greater than zero but not greater than 0.2mm, and X3 being greater than zero but not greater than 0.3mm. The gap of the first layer and the gap of the second layer are uniformly interlaced, and the gap of the second layer and the gap of the third layer are uniformly interlaced. And the distance from the gap of the first layer to the gap of the adjacent second layer, and the distance from the gap of the second layer to the gap of the adjacent third layer are both one third of the width of the polyester-film dry m
